Ive heard this term pumping before.. what is that and how would i correct that? is it that i have my threshhold set to high? cuz my thresh is only between 1.0 amd 2.5 on each band of my compressor and my limitor is between 3 and 4 db threshhold

All them compressors..and all that tweaking of said compressors and you've never heard one pump?
